At present I'm able to collapse the Geany window to the systray icon via a left mouse click upon the systray icon itself. Which on my system is located at the bottom of the screen in a tint2 panel running within MX Linux 23 FluxBox edition, a Debian based system.
I'd like to be able to collapse the window to the systray with a keyboard shortcut from within the active window. And/or from an icon or menu entry somewhere in the window. And/or, as I've seen implemented in other apps (most recently DeadBeef audio player), to have a toggle in preferences to allow closing the window to collapse it to the systray icon—instead of exiting the program. One then typically exits or "quits" the running instance via a menu entry upon right clicking the systray icon.
In the mean time, I'd welcome any presently applicable workaround suggestions folks might have.
The icon location within the tray is variable so using a click recorder app to invoke a replay of a click at its location via a shortcut triggered script or whatever would likely produce inconsistent results.
Might there be some way to fool the icon into thinking it's received a left click? Like to send a signal to trigger its function regardless of its precise location on screen?
